\section{Conclusion}

As can be seen, the possible applications of the Internet of Things are as different as the
technologies that will be needed to connect all the various entities. Although the limitations
regarding the addressing of the vast numbers of things seem to have been resolved, there are still
open issues such as the integration of multiple protocols, design of a suitable overall system
architecture, integrating semantics and supporting scalability as well as offering promising privacy
and security solutions.  Hence, the Internet of Things will require a considerable amount of
research and standardization to be conducted in the years to come.
